• Take ownership of major backend initiatives from design to long-term support
• Write and maintain scalable APIs and backend services used at a meaningful scale
• Help break down complex designs into executable components and delegate effectively when working with other developers
• Support and improve live production systems, ensuring reliability, performance, and maintainability
• Collaborate closely with leadership and senior engineers on technical direction
• Mentor other developers through code reviews, design discussions, and best practices
• Ensure adherence to the highest standards of code quality, security, and performance

What We Are Looking For
